Book excerpt: The NA48/2 experiment at the CERN SPS has collected a large sample of K to pi pi0 gamma decays.Two amplitudes contribute to these decays. The dominant one comes from Inner Bremsstrahlung (IB) in the K to pi pi0 process. The second one is given by the Direct Emission (DE) of the photon at the weak vertex from an intermediate state of the decay. The simplest radiative transitions are electric dipole (E1) and magnetic dipole (M1). Electric amplitudes can interfere with IB, and CP violation and possible non-SM effects can show up in th e corresponding interference (INT) term.In this work a sub sample of the data has been analyzed. About 120000 K to pi pi0 gamma decays, with negligible background contamination have been reconstructed in the ranges 0.2
